What would you want to happen? A completely new plot or a remake (better graphics) of the original series? And what about the cast? Should they keep the originals, or pick new voice actors? And if new, who would you pick?
...I thought of this just now, thanks to hearing Satoshi Hino (a voice actor) singing a snippet of Samurai Heart. This is that clip. Then I realized his voice would suit Sage or Cale like a glove.
My picks for a new cast, with a few songs~
Ryo: Nobutoshi Canna (pictured him singing this... this man impresses me. He's been good at singing since 1995, and he STILL keeps getting better even now! THIS. ...I also kind of picture Ryo's speaking voice sounding like Axel Almer.)
Sage: Ryotaro Okiayu (pictured him singing this and this)
Cye: Atsushi Kisaichi (pictured him singing this)
Kento: Hiroyuki Yoshino (pictured him singing this and this)
Rowen: Hisayoshi Suganuma (pictured him singing this and this)
Anubis: Ryouta Takeuchi (pictured him singing this) OR Eiji Takemoto (pictured him singing this)
Cale: Satoshi Hino (pictured him singing this, this and this)
Sekhmet: Tomokazu Sugita (pictured him singing this)
Dais: Hideo Ishikawa (pictured him singing this)
Talpa: Fumihiko Tachiki (pictured him singing this)
Saber-Stryke: Jouji Nakata (pictured him singing this... yes, this guy can sing extremely well. His voice is hot, too.)
Ancient One: Hideyuki Tanaka (pictured him singing this)
Great suggestions, Raiden! I'm not as into the anime scene as I used to be so I can't make any voice actor suggestions of my own, but in terms of plot for a new series I'd LOVE to see more of the Ronins family life explored, or the origins of how they got their armor in animated form. Even if they just showed flashbacks to these things, I'd love seeing how they lived before they got their armors.
Also, I'd like to see more about the Warlords in feudal Japan! They're very interesting characters in and of themselves and their potential was a bit wasted in the original series. This extends to Kayura, Mia, Yuli, WhiteBlaze, and the Ancient One as well. So many characters with mysterious pasts who influence the story, and aren't really explored!
I think I'd actually be disappointed if a new series was released and it was literally the same series as before, just with better animation. If I wanted to watch the first series again, I'd pop in my DVDs! Anime as a medium has come a long way since the show first came out and I think they could use a lot of what's been learned to give the series a proper update from top to bottom.
